Hi All,

Can a SIP Client A, in a active session with SIP Client B, send an Unregister messsage( means Register message with timer expiry=0) , and then comes out from the loop ?

Also if yes, the Register message(t=0) should bear same dialogue ID . But I am getting "481 Call/Transaction Does Not Exist" error message.
